Huge month-to-month jumps in gas prices can be seen in many metro areas across Northern California, according to the latest report from AAA Northern California, which tracks gas prices as a service to consumers.

According to AAA, all but four Northern California metro areas tracked by the organization saw double-digit increases at the pump over the past month. The Golden State’s average for a gallon of regular, unleaded gasoline is $3.95, up 17 cents since last month’s AAA report on August 9. For perspective, that’s 93 cents higher than California’s average price on this date last year. Among all 50 states, California has the third highest state average price for regular, unleaded gasoline. Hawaii is first and Alaska is second. Northern California gas prices are now averaging $3.93, up 14 cents from last month. In the San Francisco Bay Area, motorists can expect to pay an average price of $4.00, which is a 12-cent increase. The national average price of $3.64 is down by one cent, which is 93 cents more than the national price on this date last year, when it was $2.71. “Although demand for gasoline has fallen over the past week, which would typically help keep prices down, storms in the Gulf and East Coasts have applied upward pressure on gasoline prices in several parts of the country,” explained AAA Northern California spokesperson Matt Skryja. “In California, the state’s average price for gasoline has recently been relatively steady.”
